The 6 kA breaking capacity is the maximum prospective fault current it can safely interrupt under EN 60898; for a 20 A branch circuit in a typical industrial panel fed from a 10 kA transformer, this breaker needs upstream coordination or a current-limiting device to keep the available fault below 6 kA. At 40 °C the continuous rating derates to 18.8 A; at 55 °C it's 16.84 A. The 2-pole design switches both phase conductors on a single-phase or split-phase circuit; neutral conductor switching is not provided. The 36 mm width occupies 2 modular units — standard 18 mm per pole — so it slots into any SENTRON distribution board without surprises.","metaTitle":"Siemens 5SY6220-7CC SENTRON MCB, 2P C20 6kA, 440 V","metaDescription":"Siemens 5SY6220-7CC SENTRON miniature circuit breaker, 2-pole, C-curve, 20 A, 6 kA per EN 60898, 440 V AC.

The deciding factor is the rating: 5SY6220-7CC is a C-curve 20 A, while 5SY7210-7CC is a C-curve 10 A. If the branch circuit is designed for 10 A, swapping to a 20 A breaker may violate overcurrent protection sizing — check the conductor ampacity and load before substituting."},{"question":"Where can I buy 5SY6220-7CC?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
